This week I have been able to try out a 27 ” Tempest 3-blade, stock out of the box, with the large hole PVS plugs installed. The rig is a Puma DC with Optimax 225 Pro XS. The jackplate is up 1/4″.I removed my 26″ Trophy and installed the 27″ Tempest–no jackplate adjustments or anything else. Full tanks and all of my tackle, seats, etc, it ran 73.1 GPS at 5600 rpms. This was in fairly heavy waves, 80 degree air temp and 83 degree water temp. My previous best was 72.6 GPS with the 26″ Trophy.I plan to raise the jackplate another 1/4″ and try again. The holeshot and acceleration are excellent. Will post again after results are in.Gary Hollander
